- the subject of the invention is more particularly a display device comprising a first display element comprising a first stack of layers and a second display element comprising a second stack of layers.
- a first technology relates to an electroluminescent display based on the principle of light emission from a material following its excitation by an external electrical stress. This emission is intrinsic to the materials used, and is characterized by one or more wavelengths as well as a certain intensity. Such a display has operation in emissive mode.
- the emissive mode presents a disadvantage resulting from a degradation of the display properties in a high brightness environment. Indeed, in the case where the ambient brightness is greater than the brightness emitted by the electroluminescent display, the emitting pixels are difficult to see, and the reading of the displayed data is considerably degraded.
- a second technology relates to an electrochromic display based on the principle of optical state change of an active material, which can be related to at least one variation of transmittance, absorbance or reflectance following the application of an electrical stress to said active material.
- Such a display exhibits reflective mode operation and, as such, is characterized by a degradation of the display properties in a low light environment. Indeed, if the ambient brightness is low, the induced reflection is very small and the contrast between the colored state and the transparent state of the display is not sufficient to ensure a good display of data.
